Answer 3

Let's break down the expression:

$27 \times 3 = 81$

Now, let's simplify the expression $(20 + 7) \times 3$:

$(20 + 7) \times 3 = 27 \times 3 = 81$

So, the equation $(20 + 7) \times 3 = 81$ is true.

To express this as $?? + ?? = 81$, you can say $20 \times 3 + 7 \times 3 = 60 + 21 = 81$. Therefore, $?? + ?? = 81$ is true with $?? = 60$ and $?? = 21$.
